Restoring a Badge on a Roberts RIC1 

Those pens are great and come in different nib widths.

Nice Dom. As you know, I've been using Molotow liquid chrome pens for exactly this for a while now. My toppest, most tippety-top-top-tip is to dispense a little of the ink onto a disposable surface, and use a superfine bristle brush, smaller the better, for applying it. Any pressure at all otherwise on the pen nib results in an unwanted pool of shiny... ask me how I know...
